Definitions

  • a transportation system includes at least one transportable element, such as a pallet, platform or the like, on which loads may be supported and which has a lower face directed towards but upwardly spaced from any floor surface on which the transportable element rests.
  • At least one self-propelled transporter element is provided and is so configurated as to be accommodatable beneath the lower face of the transportable element intermediate the lower face of the latter and a floor surface on which the transportable element rests.
  • Releasable coupling means are provided for releasably coupling the elements to one another when the transporter element is accommodated beneath the lower face of the transportable element so that the the latter may be transported by the transporter element while being connected thereto.
  • Transporting systems including and particularly those for the transportation of loads, are of course not novel per se. In fact, many attempts have been made to provide such systems in order to facilitate the transportation of loads.
  • One of the most widely accepted systems in industry and commerce is the transportation of goods supported on pallets which are lifted-individually or in stacks-by forklift devices which then move them to a desired location where the single or stacked pallets are lowered to the ground-or an analogous supporting surface, whereupon the forklift is withdrawn.
  • Such forklifts comprise a self-propelled vehicle having a vertically movable supporting arm from which projections extend in parallelism with the ground plane on which the vehicle moves; hence the name forklift because there are usually two such projections side by side.
  • the arm In operation, the arm is manipulated so that the lifting projections are adjacent the ground plane between the same and the underside of the lowermost pallet, thereupon the forklift vehicle is advanced until the projections are located underneath the lowermost pallet, the arm is then lifted thereby raising the projections and the pallet or pallets which now rest on these projections, and the vehicle is then moved to a desired location where the pallet or pallets are to be deposited. Now the vehicle must of course be backed away from the pallet or pallets.
  • This widely used transportation system is fully functional for its intended purpose, namely the transportation of loads from one location to another.
  • the maneuvering involved in positioning the forklift vehicle with reference to the pallet or pallets to be lifted, and subsequently for withdrawing it from the deposited pallet or pallets is time consuming and requires a certain amount of skill from the operator.
  • it is not possible to provide a continuous flow of transported materials in one direction because, once the supported load has been deposited, the forklift vehicle must back away from it and can continue in the original direction-in which it has transported the supported loadonly after circling around the load.
  • a further known transportation system involves endless chains, ropes or the like which are mounted so as to extend along a predetermined track along which loads are to be transported, and which are driven so as to continuously advance in an endless path along this track. Carriages which support the loads to be transported are then connected in suitable manner with the advancing chain or the like and carried along thereby from one location to another at which they are disconnected.
  • An additional object of the invention is to provide such a transportation system which permits continuous free and uninterrupted flow of materials inany desired direction whenever this is desired to be accomplished.
  • a concomitant object of the invention is to'provide a transportation system which provides the aforementioned advantages but requires to be activated only when an actual need for transportation exists.
  • a transportation system which comprises, briefly stated, at least one transportable element arranged to carry loads and being provided with a lower face directed towards but upwardly spaced from a floor surface on which the transportable element rests. At least one self-propelled transporter element is so configurated as to be accommodatable beneath the lower face of the transportable element intermediate this lower face and a floor surface on which the transportable element rests. Finally, releasable couplingmeans is provided for releasably coupling the elements to one another when the transporter element is accommodated beneath the lower face for enabling transportation of the transportable element by the transporter element.
  • FIG. 1 is a somewhat diagrammatic side-elevational view
  • FIG. 2 is a view similar to FIG. I but illustrating a transportable element according to the present invention for use in conjunction with the transporter element of FIG. 1;

  • FIG/7 is a view analogous to FIG. 3 but illustrating still a further embodiment of a transporter element according to the present invention.
  • FIGS. 1-4 DESCRIPTION OF THE PREFERRED EMBODIMENTS Discussing now the drawing in detail, and firstly FIGS. 1-4 thereof, it will be seen .
  • Thatreference numeral 10 identifiesa transporter element and reference numeral ]7 identifies a transportable element (FIG. 2) '-which together are the minimum components necessary for a transportation system according to the present invention.
  • the transporter element 10 of FIG. 1 comprises. abody 11 and a frame provided with wheels 12. It is emphasized, however, thatthe wheels 12 may be provided with rollers or with articulated tracks if especially good and precise steering ability is desired to be obtained for the transporter element.
  • -'Furthermore the transporter element I0, or the vehicle 10 at it willhereafter be called for the sake of convenience, 'may also .be constructed as an air cushion vehicle, that is a vehicle of the type manufactured for instance by theBritish Hovercraft Company which is supported on the ground surface or'floorsurface F on a cushion of compressed air and is propelled along gliding on this cushion.
  • the vehicle 10 is.provided with a drive 13 to make the vehicle 10 selfpropelled.
  • the drive 13 is an electromotor -which receives its energy from a battery 13a.
  • a different drive may of course also be-used, for instance an internal combustion engine.
  • the vehicle 10 is provided withan electrically actuated guidance system 16 utilizing sensing coils l4 and 15.
  • a guidance system is described for instance in the copending U.S. Pat. application Ser. No. 804,06l assigned to the assignee of the present application, and also in US. Pat. No. 2,339,291. It is based on the principle that a guidance wire is embedded in the floor F extending along the path which the vehicle is to traverse, this guidance wire being connected with a source of alternating current so that, when such current is supplied to the guidance wire, the coils l4 and sense it and the guidance device 16 automatically causes the vehicle 10 to follow the embedded guidance wire in accordance with the sensor impulses received from the coils l4 and 15.
  • the vehicle 10 is so constructed that it can move beneath and be accommodated below a transportable element constituting one component of the novel transportation system, identified in FIG. 2 as a wheeled container 17.
  • the container 17 rests with its wheels 17a on the floor F and the distance between the latter and the downwardly directed lower face 17b of the container 17 is such that the vehicle 10 can move below the face 17b without any difficulty.
  • FIGS. 3 and 4 also shows that the width of the vehicle 10 is such that it can move between the wheels associated with the container 17.
  • a projection 18 which extends upwardly from the vehicle 10 (compare FIGS. 1 and 3) and whose height in upward direction can be adjusted as indicated by the doubleheaded arrow in FIG. 1, engages between the pivotably mounted projections 19 and 20 on the lower face 17b of the container 17 (see also FIG. 4). This takes place in that the projection 19 is lifted by and in response to contact with the projection 18 and, when the same has moved forwardly beyond it, again descends to its normal rest position shown in FIG. 2, whereupon the projection 17 abuts against the projection 20 and is confined in space between the projections 19 and 20.
  • the projections 18, 19 and 20 together constitute releasable coupling means and, when in the justdescribed position, they couple the vehicle 10 releasably with the container 17.
  • the aforementioned guide wire-and carries the container 17 along with the latter rolling on its wheels 17a.
  • An electromagnet 21 is connected in suitable and wellknown manner with the adjustable projection 18 and can be energized when the vehicle 10 with the container 17 has reached a desired location at which the container 17 is to be separated from the vehicle 10 and to be left behind.
  • Energization of the electromagnet 21 retracts the projection 18 downwardly so that it becomes freed from the projections 19 and 20 on the container 17 whereupon the vehicle 10 may move out from below the container 17, either continuing its direction of movement or reversing its direction.
  • the vehicle 10 is suitably constructed -for instance if its longitudinal dimension in the illustrated embodiment is equal to its transverse dimension--it may also move out from beneath the container 17 laterally, that is at right angle to its original direction of movement.
  • the vehicle can also be moved beneath the container 17 from lateral direction.
  • FIGS. 2 and 4 show that the lower face 17b of the vehicle 17 is also provided with rollers 22 whose positioning is shown particularly clearly in FIG. 4.
  • the purpose of these rollers, which are turnably arranged, is to facilitate proper positioning of the vehicle 10 and container 17 with reference to one another in automatic response to movement of the vehicle 10 beneath the container 17, and to make it unnecessary that the container 17 is located at a precise position on the track along which the vehicle 10 moves.
  • the distance a between transversely spaced ones of the rollers 22 (compare FIG.
  • the vehicle 10 is provided with metal guards 25 (see FIG. 3) which correspond to the inclined surfaces 23 and 24 and protect the vehicle against damage upon contact with the rollers 22.
  • the rollers 22 and the guide surfaces 23, 24 (or the protectors 25) may be reversed, that is that the rollers 22 may be provided on the vehicle 10 and the inclined guide surfaces 23, 24 or protectors 25 may be provided on the container 17 is desired.
  • the rollers may be completely omitted and both the vehicle 10 and the container 17 be provided with inclined cooperating guide surfaces.
  • the guide surfaces may be omitted and only the rollers provided.
  • FIG. 5 A further possibility for proper alignment of the vehicle with reference to the container is identified with reference numeral 5 in FIG. 5 where the vehicle has the designation 30.
  • the vehicle 30 carries at its front side a light source 26 and in addition a receiver 27, for instance a photoelectric diode.
  • the container 17 is provided with light-reflective elements 28, for instance metallic elements, which reflect light is suing from the light source 26 back to the receiver 27 depending upon the relative position of the vehicle 30 and the container 17.
  • This generates signals in the receiver 27 which in known manner are transmitted to and influence the guidance and control device 16 so that thereby proper alignment of the vehicle 30 and the container 17 relative to one another is obtained.
  • Other electrical guidance devices or aligning devices are also possible and well known to those skilled in the art.
  • FIG. 6 shows that the container, here identified with reference numeral 170, may instead of wheels 17a be provided with gliders 29.
  • FIG. 6 is self-explanatory and it will be appreciated that the gliders 29 may be constructed in various different ways as long as they permit easy gliding of the container along the floor F in response to motive power supplied by the vehicle 10 or 30.

  • This bumper arrangement may be in form of a telescopic spring 38 which, if it contacts an obstacle, is telescoped and shifts an abutment 39 which in turn activates a switch 40 which deactivates the drive 13 of the vehicle 10.
  • the vehicle 10 may also be provided, as shown in FIG. 7, with a bumper 40 which is mounted on the vehicle via spring elements 41. If the bumper 40 is provided with inclined surfaces, for instance in the manner shown in FIG. 7, it may itself serve as the aligning or guiding means for facilitating aligning of the vehicle 10 and the container [7 with reference to one another, in addition to or in lieu of the elements 22, 23, 24 and 25 of FIGS. l-4, or the photoelectric construction shown in FIG. 5.
